Early symptom of nasopharyngeal cancer?

summary

Naso laryngeal carcinoma is one of the malignant tumors. The incidence rate is obviously in the region. For example, some areas with heavy humidity or serious environmental pollution often have higher incidence rate. Nasopharyngeal carcinoma (NPC) is a great threat to people's health. People living in Guangdong and Guangxi, where NPC occurs frequently, should know more about the early symptoms of NPC? In order to achieve early detection and early treatment.

Early symptom of nasopharyngeal cancer?

1. Nasal obstruction: nasal obstruction is a common early manifestation of nasopharyngeal carcinoma. Most of them are unilateral nasal obstruction. When the nasopharyngeal tumor is enlarged, bilateral nasal obstruction may appear.

2. Headache: about 70% of NPC patients have headache symptoms at the time of initial diagnosis. The headache symptom of nasopharyngeal carcinoma often presents as unilateral persistent pain, mostly in the temporal and parietal region. The headache of nasopharyngeal carcinoma is mostly related to the invasion of skull base bone, nerves and blood vessels by cancer tissue.

3. Bloody nose and epistaxis: bloody nose is an early symptom of nasopharyngeal carcinoma, characterized by blood in the nose, or by sucking blood from the mouth. Epistaxis often occurs after getting up in the morning. When the amount of blood in the nose is not much, it is often neglected by the patients and mistaken for rhinitis or sinusitis.
